After being wounded during the Civil War, Sassoon returned to Aston-upon-Lum with the desire to pursue the seat in 668. Due to unforeseen circumstances he would get the seat in 667 instead after Cosmo Maltravers resigned. In a break from his usual tendancies, shortly after getting into office he would join the DPPK as one of their few Conservative members. He later joined the NUP. As he continued in his political career, he would begin to subscribe to the idea of "natural order" - the belief that everything in life had a place and that place must be maintained at any and all cost. It marked a swift turn to a more conservative path for Sassoon, who had hitherto been rather reserved about his full opinions.
